Everyone Dietrich
I made a video adptor in order to excange all the video to the old movie. By this machine , all the woman in the video are able to be seen like a Marlene Dietrich. See the circuit! This is a simple low pass filter. With this circuit color signal in the video signal is cut, and remains only brightness signal. So the vision becomes only white and black.
"""Very sorry this circuit is effective only in Japan and U.S.A. where uses NTSC system for television.""""
